FOR USE IN THE MANUFACTURE OF BISCUITS ANI) THE LIKE.

Application filed February 8, 1922,

This invention relates to machines for use in the manufacture of biscuits and the like, and of the general class in which a sheet of dough, paste or similar substance is passed on a conveyor or web o-ver a table beneath a series of combined 'cutters and embossers which may serve also as ejectors, and is conveyed thence by said conveyor for example to be delivered to pans or equivalents, in 'which Ythey are delivered to an oven or otherwise dealt with,

The invention comprises a number of'novel or improved features of construction, detail and combinations of parts whereby the general construction of the machine is siinplified, its function facilitated, andV the operation rendered substantially continuous, the main feature of the invention consisting of a cutter head adapted toybe rocked through a large arc about a pivot in the base of. the machine as distinct'from' known devices in which two distinct movements viz. ay` horizontal and vertical are. given to said. cutter head. Tliesaid cutter head ters, embossers and. ejectors. f The invention is hereinafter described and pointed. out. iii

carries the cut-' Fig'. 1a is the sheet of dough p is fofthe class referred Serial No. 534,910, and in Great Britain February 16, 1921.

view of part of which is also shown in Fig. 4.

Each cam 7 -and '8i (two beinglherein shown) is mounted on a common shaft-9`I and co-operates with one arm 10, 11 respectively of` a double bellcran'k orlever keyedas at 12 to a shaft 18,- said cams bearing against rollers 14, and 15 carried by said; arms whichA are shown asf-braced together or stiifened by lateralbolts 16 Vengaging lugs' 17 on the arms andtensioned by nuts 18. The bell-crank also includes an arm 19-provi'ding a slotted or adjustable sliding bearing QO'for oneiend of a link 21, the other' endof-'which has a similar bearing at 22, in one arm 23'- of'another Vbell-crank pivote'd to the ymachine frame latll'fan'd the other' arm 25 of-which i'sjconnected by a ,rod or link26 to al bracket 26a on one ofthe frames 5 atla point well above its',- fulcrum. The shaft Qliis carried across the machine., and another leverY 25 with similar rod Q6 are repeated at the other side of machine. p

By means of the adjustable sliding bearingsQO and-221the extentv ofl angular rocking `movement of the frames may be varie'daccording to requirements. v

The construction and arrangement ofthe 'cams 7 andv8, lever arms 10, 11 androllers 14, 15" is such that nebst-motion ory slackvness exists between these parts andthe-movement ofthe rocking frames 5 is positive in both directions.

The cut'tiiigtable iis mounted between the frames 5- and'is stationary therein asregards any vertical adiustment, being carried by a cross frame 27 bolted to said'franies. Fig. 1a is a cross sectionof the table 4 andshows a conventionalconstruction, comprising the tablev frame lia, top ib with interposed resilient-buffersfic and blockflidover which is stretched the usual cloth or like covering 4e secured by screws 4f.

The cutters 2 are mounted in the rocking frames 5 in a. substantially known manner, that is to say, they are carried by a crosshead 28 adapted for vertical sliding movement in the frames, to which crosshead motion is imparted to perform the cutting operation by `means ot a rod 29 (one at each side oit the machine) connected to a sheave 30 in which Works an eccentric 3l mounted on the same shaft 6 as that about Which the rocking iframes 5 and associated parts have movement.

Fig. 5 shows the mounting of the cut-ters 2 in the cross head 28 by means of a trame 28L extending` across the machine and carried by bolts 28'J (one shown in said figure) eX- tending through slots 28c in the crosshead.

The cutter cross-head 28 is adjustably mounted on said rods 29 as at 32, and controlled as by means of Worm gear 33 operated by a hand Wheel 34 to vary its stroke and the position oit' the cutters in relation to the table and consequently the depth of cut of the cutters When necessary. In Figs. 3 and 5, 35 designates the scrap or stripper plate commonly provided in this class of machine and resiliently suspended by means ot bolts 35a and springs 35b from the cutter cross head frame 28a. v

The embossers and ejectors 3 are contained Within the critters and mounter independently thereof as is customary in this class of apl' paratus, this arrangement being shown in Fig. 5 in Which said ejectors which also normally act as embossers are shown as carried by rods 32L attached by nuts 3b to a frame 52C which is connected at its ends by rods 3d (one shown in Fig. 5) suspended from another crosshead 36, adapted for vertical sliding movement in the rocking frames 5. The ejectors and embossers are given their necessary movements by means of a pair of rocking arms 37 one at each side at the base of the machine. One end of each of said arms is fulcrummed to the machine trame at 38 and to a suitable part of said arm is coupled the lower end of a rod 39. (Fig. 3) the upper end ci which is adjustably attached as at 40 to the embosser-crosshead 36. Worm gear 41 operated by hand Wheels 42 and 42a is shown for effecting the adjustment to control the degree of relative movement between the embossers and cutters for embossing and ejecting purposes according to requirements.

The adjustments of both the cutter crosshead and the embosser cross-head are preferably effected from the same side of the machine at different points or alternatively also from both sides, for Which purpose as regards the embosser cross-head the hand Wheel 42a and shaft 42h effects the adjustment at the opposite-side of the machine and when the adjustments at the respective sides have been made the two hand'wheels may be locked together by castellation 42C or equivalents in order that further adjustments may be effected simultaneously at beth sides. The adjustments for the cuttercross-head are similarly arranged (see hand-Wheel V34).

The tree end of each rocking arm 37 carries a roller 43 acted on by a cam 44 (Fig. l) mounted on the same shaft 9 as the. cams 7, 8 for rocking the frames 5. The said rollers 48 are acted upon by a compensating spring 45 which is shown as coiled about a rod 46 connected at its uper end at 46a to the cutter head 28 and at its lower end slidably engaging a lug 4? on a bar 48 the lowerend oi? which is attached to the rocking arm 87 at point 482L and through the upper end ot which the rod 46 slides, the said spring 45 bearing at opposite ends between lugs 49 and 50 on said bar. rihs construction compensates `for any difference oi relative movement between the. cutter cross-head 28 and the embosser cross-head 46: it also permits the maintenance of operative engagement between the cams 44 and rollers 43 in spite ci the relative rocking movements of the frames 5 and arms 37 respectively, and relieves the cam-motion of undue stress during the Working stroke. Y i,

Where it is required to operate the machine Without using` the embossing mechanism, it is usual to attach to an ejector plate a Weight Which, vas the cutters descend, holds said ejectorplate'on the dough While the biscuits are being cut out from the sheet of dough and then, as the cutters rise from the dough, ejects the cut biscuits vand scrap. lhere the cutters and associated parts are rocked during the cutting operation, as in the present inventionjit is desirable that such Weight should be replaced by a cross bar 5l, adapted to slide vertically in the side cutter trames 5 and loaded with the desired pressure byY a number of compressed springs so that the rocking portion of the machine may be as light as possible. When so operating the machine the embosser cross head 36 is put out of Vaction by disconnecting its operating rods 39 and remains stationary. A rod 52a (one at each side) is connected to the cutter cross head 28 and extends upwards through the bar 51 above Which it is surrounded by a coiled spring 52 held by a nut 52f. On descent ofV said cross head, the rod 52EL by the action of the spring 52 pulls doWn the cross bar 5l untilV a lug 52d integral therewith engages an abutment 52a on the side frame 5 and through a connecting rod 52b betweenthe bar 5l and the stripper plate 35 the latter is held at a predetermined distance from the cuttingv table 4 While the cutting takes place. When' embossing the rod 521 is dispensed With. The stripper plate remains in this positionduring the first part of the return movement ol" the cutters 2 thereby stripping the scrap, and the ejectors remaining stationary and biscuits are afterwards ejected.

The cams 7 and 8 and 44E respectively for operating the rocking frames 5 and embosser cross-head 36 and the shaft 6 for operating the cutter cross-head 28 are driven through a suitable train of spur-gear 53, 54, 55, from a main drive-shaft 56.

In the claims which follow the terms biscuits and dough7 are held to include any like product, or material from which such product is produced, within the capabilities of the mechanism forming the subject matter of said claims.
